FAST 2GB DDR Kits - Part 2

Performance Comparisons

Performance of the six 2GB memory kits was compared to the three 2GB kits tested in Part 1 of the 2GB roundup. Results are also generally comparable to earlier results on the nForce3 and nForce4 testbed using the AGP and PCIe versions of the NVIDIA 6800 video card. While we retested the first three 2GB kits in the revised test bed using the NVIDIA 7800GTX and the latest platform and video drivers, the results are not radically different from those in the old test bed, as long as you don't make too much of small percentage difference in memory performance. However, we have only reported results on the newest revised test bed to prevent any confusion about the influence of video card and drivers on the final results.

Searching for the Memory Holy Grail – Part 2

All nine of the 2GB DDR kits were compared at 200x12 (2.4Ghz, DDR400), 218x11 (2.4Ghz, DDR438), 240x10 (2.4Ghz, DDR480), 266x9 (2.4Ghz, DDR533) and the Highest Memory Performance Settings that we could reach. With a constant CPU speed, memory comparisons (except for top performance) show the true impact of faster speed and slower memory timings on memory performance.

Performance results for the fastest 2x512MB (1GB) kit that we have tested are included for reference at Highest Performance only. Including our standard OCZ 3200 Platinum R2, based on TCCD chips, allows you to compare performance at the top to the best 2x512MB kit that we have tested. For more comparisons to 1GB kits, please refer to earlier memory reviews linked above.

Keep in mind that Highest Performance is not comparing memory at the same multipliers. The factor of the overclocking abilities of the 400+ used for benchmarking comes in to play. For instance, a memory that reaches its highest overclock at a somewhat low clock frequency can actually have that clock frequency fall in the processor OC capabilities where it can run at a higher multiplier. The definition of Highest Performance is the highest clock frequency and multiplier that we could run with the tested memory and the standard 4000+ CPU. For a true "apples to apples" comparison, you need to look at comparisons at the same speed and multiplier.

Results of the retest of the first three 2GB kits are in green, the six new 2GB kits are in dark blue, and the Reference 1GB OCZ 3200 Platinum R2 results are in gold.
